section has eight separate combustion chambers. The compressor is driven by a two-stage turbine
mounted on the aft end of the compressor rotor shaft.
The power turbine section is also a two-stage turbine, which mounts on the front end of the
turbine shaft. The turbine shaft extends out the exhaust end of the engine.
The engine fuel system has a hydromechanical fuel control with a metering and computing
section that schedules fuel flow. Internal cooling and pressurization are maintained by compressor bleed
air. Compressor bleed air is also used to prevent ice from forming on the engine inlet surfaces. All
components of the lubrication system are mounted on the engine. The oil system is a dry-sump type.
The engine electrical system consists of the torque sensing system, ignition system, and
turbine inlet temperature system.
